[0032] The utility model mainly discloses a clean hydrogen supply machine, the basic physical and chemical principles involved in which are already understood by those with ordinary knowledge in the relevant technical field, so no complete description is given below. At the same time, the accompanying drawings in the following text only express the structural schematic diagram related to the utility model, and are not and do not need to be fully drawn according to the actual size, which is explained in advance.

[0033] In order to achieve at least one advantage of the present invention, a preferred embodiment of the present invention is a clean hydrogen supply machine, such as Figure 1 The clean hydrogen supply machine includes a water tank 700, an electrolysis device 500, a first pipeline 100, a second pipeline 200, a third pipeline 300, a heat sink 600, and a DC power supply 800. Figure 1 shown.

[0034] sink 700

[0035] like Figure 2 As shown, the water tank 700 includes a first water inlet 711, a water outlet 712, a drain 713, and a water-oxygen inlet 731. The water tank 700 is also provided with a minimum water level 705 and a maximum water level 706. The first water inlet 711 is provided above the maximum water level 706 for injecting pure water. The water outlet 712 is used to output the pure water in the water tank 700 to the electrolysis device 500 for electrolysis, and the drain 713 is used to discharge the water in the water tank 700 so that the water tank 700 is clear. The water-oxygen inlet 731 is used to introduce a water-oxygen mixture rich in oxygen after electrolysis. The clean hydrogen supply machine works only when the pure water is between the minimum water level 705 and the maximum water level 706. Therefore, the heights of the water outlet 712 and the drain 713 are not higher than the minimum water level 705.

[0036] Preferably, the water tank 700 is further provided with a water level sensor for detecting the water level of the pure water in the water tank 700 , and the operation of the clean hydrogen supply machine is allowed only when the pure water is confirmed to be between the minimum water level 705 and the maximum water level 706 .

[0037] Electrolysis device 500

[0038] Please see Figure 3 The electrolysis device 500 is disposed on one side of the water tank 700, and includes a proton membrane electrolyzer 510, and a second water inlet 501 connected to the proton membrane electrolyzer 510, a water oxygen outlet 502, and a hydrogen outlet 521. The second water inlet 501 is used to receive pure water from the water tank 700. More specifically, one end of the first pipeline 100 is connected to the water outlet 712 of the water tank 700, and the other end is connected to the second water inlet 501. Therefore, the pure water of the water tank 700 enters the electrolysis device 500 through the water outlet 712, the first pipeline 100, and the second water inlet 501.

[0039] The utility model uses proton membrane electrolysis to generate hydrogen and oxygen. The basic principle is to plate anode and cathode metals on both sides of the proton membrane, and then electrolyze pure water to generate hydrogen and oxygen after power is turned on. Since the pores of the proton membrane are extremely small, only hydrogen after electrolysis of pure water is allowed to pass through the proton membrane to the other side and be discharged from the hydrogen outlet 521. In this way, pure hydrogen without impurities can be supplied to other equipment for use.

[0040] The oxygen after electrolysis is blocked on this side of the proton membrane, mixed with pure water and discharged from the water oxygen outlet 502. Therefore, the water oxygen outlet 502 and the hydrogen outlet 521 are arranged on both sides of the proton membrane electrolyzer 510, and are not connected to each other. The second water inlet 501 and the water oxygen outlet 502 are arranged on the same side, and the height of the water oxygen outlet 502 is preferably higher than the second water inlet 501, so that due to the buoyancy principle, the oxygen generated by electrolysis can be automatically output through the water oxygen outlet 502, and will not be reversely output from the second water inlet 501.

[0041] Any electrolysis device will generate a large amount of heat energy when electrolyzing water to generate hydrogen and oxygen. The higher the electrolysis efficiency, the greater the heat energy generated. This is also a common problem of existing hydrogen-oxygen machines. They cannot be turned on for a long time and must be shut down intermittently to cool down to avoid damage to the machine. Another feature of the utility model also solves this problem. For the proton membrane electrolyzer 510, the electrolysis heat energy is mainly concentrated on the oxygen side. Therefore, the water-oxygen mixture output through the water-oxygen outlet 502 will not directly enter the water tank 700, but will enter the heat dissipation device 600 through the second pipeline 200.

[0042] The electrolysis device 500 is preferably arranged below the water tank 700. The pure water in the water tank 700 can automatically flow into the electrolysis device 500 through the first pipeline 100 due to gravity, maintaining a sufficient amount of pure water in the proton membrane electrolyzer 510 to protect the proton membrane and prevent it from burning after sudden power-on. Of course, the electrolysis device 500 can also be arranged beside the water tank 700, as long as the second water inlet 501 is not higher than the water outlet 712 of the water tank 700. More preferably, Figure 3As shown, the first pipeline 100 may also be provided with a pump 110 to pressurize the pure water into the electrolysis device 500 .

[0043] The proton membrane electrolyzer 510 is a relatively expensive device. To protect the proton membrane electrolyzer 510, a filter 120 may be further provided in the first pipeline 100. Figure 3 As shown, pure water is filtered to remove minerals, electrolytes, and any unnecessary impurities before being introduced into the electrolysis device 500 for electrolysis.

[0044] For applications with a large flow rate of hydrogen demand, multiple proton membrane electrolysis units can be used. The proton membrane electrolyzer 510 proposed in the present invention includes n groups of proton membrane electrolysis units, each of which has a rated operating voltage of m volts, and the maximum output voltage of the DC power supply 800 is P volts, where n*m≈P. More specifically, the rated operating voltage of each proton membrane electrolysis unit used in the present invention is 3 volts (m=3). If a DC power supply 800 with a maximum output voltage of 12 volts (P=12) is used, 4 groups (n=4) of proton membrane electrolysis units can be connected in series to achieve the best electrolysis efficiency. Of course, only 2 to 3 groups of proton membrane electrolysis units can be connected in series, or more than 4 groups of proton membrane electrolysis units can be connected in series, as long as a smaller or larger DC power supply 800 is replaced, or the output voltage of the DC power supply 800 is changed.

[0045] First pipeline 100

[0046] Please see Figure 1 , Figure 2 and Figure 3 The first pipeline 100 is used to connect the water tank 700 and the electrolysis device 500, and transport the pure water in the water tank 700 to the electrolysis device 500 for electrolysis. More specifically, one end of the first pipeline 100 is connected to the water outlet 712 of the water tank 700, and the other end is connected to the second water inlet 501 of the electrolysis device 500. Preferably, the height of the water outlet 712 is not lower than the second water inlet 501, so that the pure water in the water tank 700 can automatically flow into the electrolysis device 500 due to gravity.

[0047] In a preferred embodiment, if Figure 3 As shown, the first pipeline 100 further includes a one-way valve 130 , which is disposed near the electrolysis device 500 to prevent the water in the electrolysis device 500 from flowing back into the water tank 700 as much as possible.

[0048] In a preferred embodiment, if Figure 3 As shown, the first pipeline 100 may also be provided with a pump 110 to pressurize the pure water into the electrolysis device 500 .

[0049] In a preferred embodiment, if Figure 3 As shown, the first pipeline 100 may further be provided with a filter 120 to filter the pure water, remove minerals, electrolytes, and any unnecessary impurities, and then introduce the pure water into the electrolysis device 500 .

[0050] Second pipeline 200

[0051] See also Figure 1 , Figure 3 and Figure 4 , the second pipeline 200 is used to connect the electrolysis device 500 and the heat sink 600, and transmit the water-oxygen mixture generated by the electrolysis device 500 to the heat sink 600. More specifically, one end of the second pipeline 200 is connected to the water-oxygen outlet 502 of the electrolysis device 500, and the other end is connected to the high-temperature water inlet 610 of the heat sink 600. Since the water temperature of the water-oxygen outlet 502 is relatively high due to proton membrane electrolysis, according to the principle of thermal convection, the height of the high-temperature water inlet 610 is higher than that of the water-oxygen outlet 502, so that the water-oxygen mixture of the water-oxygen outlet 502 can more easily flow into the high-temperature water inlet 610 of the heat sink 600 due to temperature, gravity or buoyancy.

[0052] The third pipeline 300

[0053] See also Figure 1 , Figure 3 and Figure 4 The third pipeline 300 is used to connect the heat sink 600 and the water tank 700, and transport the water-oxygen mixture cooled by the heat sink 600 to the water tank 700. More specifically, one end of the third pipeline 300 is connected to the low-temperature water inlet 620 of the heat sink 600, and the other end is connected to the water-oxygen inlet 731 of the water tank 700. Preferably, the height of the water-oxygen inlet 731 is higher than that of the low-temperature water inlet 620, so that the oxygen in the low-temperature water inlet 620 can more easily flow into the water-oxygen inlet 731 of the water tank 700 due to temperature or buoyancy.

[0054] Fourth pipeline 400

[0055] In a preferred embodiment, if Figure 1 and Figure 3 As shown, the clean hydrogen supply machine proposed in the present invention further includes a fourth pipeline 400 connected to the hydrogen outlet 521 to guide the generated pure hydrogen to a desired location.

[0056] Since pure hydrogen is generated by electrolysis of pure water, it is also rich in water vapor. In a preferred embodiment, the fourth pipeline 400 further comprises a condenser 410 to condense and filter out the water vapor in the hydrogen generated by electrolysis, so that relatively dry pure hydrogen can be output.

[0057] Heat sink 600

[0058] See also Figure 4 The heat dissipation device 600 includes a heat dissipation pipeline 630 and a fan 640. A high-temperature water inlet 610 and a low-temperature water inlet 620 are respectively provided at both ends of the heat dissipation pipeline 630. The high-temperature water inlet 610 is connected to the water-oxygen outlet 502 of the electrolysis device 500 through the second pipeline 200, and the low-temperature water inlet 620 is connected to the water-oxygen inlet 731 of the water tank 700 through the third pipeline 300. The high-temperature water-oxygen mixture flowing out of the water-oxygen outlet 502 of the electrolysis device 500 enters the high-temperature water inlet 610 through the second pipeline 200, is cooled by the heat dissipation pipeline 630, and then flows out from the low-temperature water inlet 620, and then enters the water tank 700 from the water-oxygen inlet 731 through the third pipeline 300.

[0059] Preferably, the heat dissipation device 600 further includes a plurality of heat dissipation fins 650 , and the heat dissipation pipe 630 is passed through the heat dissipation fins 650 , so as to improve the heat dissipation efficiency through heat conduction.

[0060] The configuration relationship between the fan 640 and the heat dissipation pipe 630 is a key point. The air sucked in or the air flow blown out by the fan 640 should preferably pass through the heat dissipation pipe 630 with the largest area, so as to achieve the best heat dissipation effect through convection. If the heat dissipation pipe 630 is set vertically, the fan 640 is configured on the left or right side of the heat dissipation pipe 630. If the heat dissipation pipe 630 is set horizontally, the fan 640 is configured above or below the heat dissipation pipe 630.

[0061] Due to the principle that hot air rises, it is preferred that the heat sink 600 is disposed above or below the electrolysis device 500, so that the electrolysis device 500 is disposed in the air flow path of the air sucked in or blown out by the fan 640, which is more conducive to taking away the heat energy generated by the electrolysis device 500 when it is working.

[0062] DC Power Supply 800

[0063] See also Figure 1 The DC power supply 800 is electrically connected to the electrolysis device 500 and the heat dissipation device 600, and mainly provides the DC power required for the operation of the proton membrane electrolyzer 510 and the fan 640, and also provides DC power to other electronic components and sensors. However, the power consumption of the proton membrane electrolyzer 510 is the largest. Therefore, the DC power supply 800 will also generate a lot of heat energy when working, which needs heat dissipation treatment.

[0064] A normal DC power supply will have a small cooling fan, but for a DC power supply running at full speed, such a small fan has a poor cooling effect, so the fan 640 of the heat dissipation device 600 proposed in the present invention also cools the DC power supply 800.

[0065] The configuration relationship between the fan 640 and the DC power supply 800 is a key point. The DC power supply 800 should be placed in the airflow path of the air sucked or blown out by the fan 640 to achieve the best heat dissipation effect through convection. If the fan 640 is set vertically, the airflow path is horizontal, and the DC power supply 800 is placed on the left or right side of the fan 640. If the fan 640 is set horizontally, the airflow path is vertical, and the DC power supply 800 is placed above or below the fan 640.

[0066] The clean hydrogen supply machine provided by the utility model can generate pure hydrogen, and has the characteristics of high hydrogen gas output efficiency, convenient and safe operation, low heat generation, and long-term continuous use. It is suitable for use in homes, offices, and even factories.

However, any equivalent changes and modifications made to the above embodiments based on the technical essence of the present invention without departing from the content of the technical solution of the present invention are still within the scope of the technical solution of the present invention.
